Hi Andy,
Could you post a pcap showing the whole flow from the B2B perspective -
it will simpler to understand the problem.

Hello
I am trying to use the B2B marketing scenario example as shown here
<https://www.opensips.org/Documentation/Tutorials-B2BUA#toc14> with
the exception that I have another OpenSIPS instance running between
B2B and other parties except MediaServer.
opensipsctl fifo b2b_trigger_scenario marketing
sip:[email protected] <mailto:sip%3a%[email protected]>
sip:[email protected] <mailto:sip%3A%[email protected]>
sip:[email protected] <mailto:sip%3a%[email protected]>
This executes as something like:
a) B2B sends INVITE to Proxy (my.domain.com <http://my.domain.com>)
towards 4712345.
b) Proxy sends this call to PSTN-GW and it works
c) B2B sends INVITE to MediaServer (1.2.3.4) and RTP flows correctly.
d) B2B received BYE from MediaServer
e) B2B sends INVITE to Proxy (my.domain.com <http://my.domain.com>)
towards 4723456
f) Proxy sends this call to PSTN-GW
g) PSTN-GW responds 491 Request Pending for this call
My B2B is running the script found here
<http://pastebin.com/gjYZjQq6> and the Proxy is running the script
found here <http://pastebin.com/7Zge8jZM>
RFC 3261, 14.1 UAC Behavior States:
UAC MUST NOT initiate a new INVITE transaction within a dialog while
another INVITE transaction is in progress in either direction. If
there is an ongoing INVITE client transaction, the TU MUST wait until
the transaction reaches the completed or terminated state before
initiating the new INVITE.
Can anybody help me spot where my error is?
Thank you!
Kind regards,
Andy
